Given numbers are 532,170,643,128,480

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 532,170,643,128,480 is 2791340160.

Find LCM of 532,170,643,128,480 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 2 x 2 x 2 x 2 x 5 x 133 x 17 x 643 x 4 x 3 = 2791340160

Therefore, the lowest common multiple of 532,170,643,128,480 is 2791340160.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

532 x 170 x 643 x 128 x 480 = 3572915404800

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

532 : 1, 2, 4, 7, 14, 19, 28, 38, 76, 133, 266, 532

170 : 1, 2, 5, 10, 17, 34, 85, 170

643 : 1, 643

128 : 1, 2, 4, 8, 16, 32, 64, 128

480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 532,170,643,128,480, is 1.

Now, the common factors can be found like this.

532:2x 2x 7x 19

170:2x 5x 17

643:643

128:2x 2x 2x 2x 2x 2x 2

480:2x 2x 2x 2x 2x 3x 5

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2x 2x 2x 2x 2x 2x 2x 5 = 1280

Therefore, the value for common factors is 1280.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 3572915404800/(1x1280)

LCM = 3572915404800/1280

LCM = 2791340160

Thus, we can understand that the LCM of 532,170,643,128,480 is 2791340160.
